Disclaimer

According to German law (see the decision of the Landgericht Hamburg from the 12th of May 1998, file number: 312 O 85/98) the editor of a web site can be made responsible for the contents of other sites, which are referred to with hyperlinks, unless he excludes his responsibility explicitly.Despite thorough editorial controls we therefore exclude our liability for external contents, which are referred to on the GMS site. We are responsible for external contents only in the case that on the one hand we receive positive knowledge of the illegality of the contents and on the other hand have the technical possibility to avoid the usage of the contents at reasonable efforts.We also exclude our liability in principle for external contents, which have been changed after our referring hyperlink was set.This disclaimer of warranty refers to all hyperlinks on the German Medical Science web site.
